2007 Pontiac G6 sedan

For 2007, the G6 gets a major engine shuffle; the top-of-the-line GTP gets a new, more powerful V-6 engine and 6-speed automatic transmission, while last year's 3.9-liter GTP engine is now optional on the GT model. Side curtain air bags are now standard on all G6 coupes and sedans, while the GT models get a revised power steering system. The GTP version of the hard-top convertible is discontinued, leaving only the GT version for those that want to drive with the top down.
